IEC 60670-1:2021 Clause 15.2 and 15.5 Electrical Casing Compression Test Device

The LS-B21 electrical enclosure compression test apparatus is used to test the compression resistance and structural stability of electrical mounting boxes and enclosures, ensuring they meet usage requirements under specific environmental conditions and external forces. The apparatus first treats the sample in a specific temperature environment. After the sample cools to ambient temperature, it is placed between dedicated support structures, and a specified pressure is applied steadily and maintained for a corresponding duration. After the test is completed and the pressure is released for a period of time, the deformation of the sample is measured to determine whether the enclosure has undergone deformation or damage that affects its use or fails to meet requirements. The apparatus can precisely control the pressure and application time, simulating the pressure scenarios that electrical enclosures may encounter during actual storage, transportation, or use, providing a scientific basis for product quality verification and ensuring the reliability of the mechanical properties of electrical enclosures.

Standards:

Specification:
• Control method: touch screen + PLC control;
• Compression method: electric;
• Compression force value: 50-1000N (can be set), sensor accuracy: 1%FS;
• Compression time: 1-99min(s) can be set arbitrarily. After the compression time is up, the pressure will be automatically relieved and withdrawn. The deformation was measured 1 hour after the load was removed.
• Displacement resolution: 1mm

Typical Applications:
• Electrical enclosure manufacturers conduct compression resistance testing on their mounting boxes and enclosures before shipment.
• Electrical equipment manufacturers conduct compliance testing on enclosure components to ensure overall product reliability.
• Third-party testing organizations provide compression performance testing and certification services for electrical enclosures according to relevant standards.
• During the R&D phase of electrical enclosures, performance verification of structural design is conducted to optimize material selection and structural strength design.
• Quality supervision departments conduct random sampling inspections of electrical enclosure products circulating in the market to standardize industry quality standards.
• Lighting appliance component suppliers conduct specialized compression performance tests on lighting fixture mounting boxes and enclosures.
